If you are looking for the best technology to start your Web application project, then you should definitely consider React JavaScript.

ReactJS is an open-source JavaScript library designed by Facebook in 2011 for creating rich and engaging web apps fast with minimal coding.

React is continuously gaining popularity among developers and businesses. Here’s why.

With ReactJS developers can build user interfaces with lightweight, SEO-friendly, and fast-loading single-page applications. React basically gives developers the ability to work with a virtual browser that is more friendly than the real browser.

What’s different about React

Before ReactJS was introduced, most developers did a lot of coding. It brought on challenges, especially when crafting components that change frequently.

React JavaScript framework solves these issues, helping developers break down complex components, and allowing code reuse for faster project deployment.

React’s official definition states that it’s a JavaScript library for building User Interfaces. This definition implies two things:

  1. React is a JavaScript library. It’s not a framework. It focuses on just doing one thing very well.

  2. What React does very well is "building user interfaces". A User Interface is anything you put in front of users and that they can interact with.

Web browsers understand JavaScript, so React translates the code (declarative descriptions written in the React language) to actual User Interfaces in the browser.

The core objective of ReactJS is to provide the best possible rendering performance, focusing on individual components. Instead of working on the entire web app, ReactJS allows a developer to break down the complex UI into simpler components.

Why Businesses use React

Part of React’s huge popularity comes from the fact that top corporations such as Facebook, PayPal, Uber, Instagram, and Airbnb use it to solve user interface-related issues.

In the tech-driven arena, entrepreneurs and developers are always looking for better methods of giving their businesses a competitive advantage, and React can help with that.

React has some major attributes that drive its popularity:

1. Better User Experience

ReactJS allows enterprises to offer better UI to enhance user experiences that result in better user engagement, higher click-through rates, and conversions.

2. Better Performance

ReactJS helps to prevent updating of DOM, which means that the apps will be faster and deliver better UX.

3. Efficiency

ReactJS was designed to help improve the total rendered pages from the website server

Why React is a favorite among Developers

1. Clean Abstraction

This is one of the most impressive features of ReactJS. It does not require intensive knowledge of special design architectures. You can build using this framework by simply understanding the life cycles, props, and states of the components.

2. Easy Learning Curve

Developers find it easy to learn ReactJS. React is just JavaScript, there is a very small API to learn, just a few functions and how to use them. A JavaScript developer can become a productive React developer in a few hours.

3. Reusable components

Developers can reuse these components, which means they can also reduce the codes. This is beneficial for developers in reusing their codebase. At the same time, it is extremely advantageous for businesses to scale their application.

The idea of components is what makes ReactJS unique. Instead of worrying about the entire web app, it makes it possible to break the complex UI/UX development into simpler components. This is crucial in making every component more intuitive.

4 Enhanced User experience

React uses Virtual DOM that makes the app fast. The idea of Virtual DOM allows ReactJS to know when exactly to re-render or when to ignore some specific pieces of DOM because it can detect when the data has changed. A UI that reacts promptly is crucial in enhancing the user experience.

React Javascript Vs React Native

There is always confusion between ReactJS and React Native. We’ll clear this confusion to help you in your journey to deciding whether React is the right tool for you.

After the successful release of ReactJS, Facebook released a fine-tuned framework called React Native.

The basic difference is that ReactJS helps in Web development, while React Native framework helps in mobile application development.


To get your goals from your business apps, it is important to ensure they are crafted professionally and in line with the best practices. Working with a React Development company will help you to craft achievable goals while demonstrating how your business can use this technology to accelerate growth, raise conversions, and cut costs.
